Can the Fever Cause a Seizure?

A rapidly rising fever may cause a seizure (febrile convulsion). This may occur in patients with roseola during the febrile portion of their illness. Febrile seizures (convulsions associated with fever) are common in children between 18 months to 3 years of age. Studies indicate that approximately 10%-15% of children with roseola will have a febrile convulsion.
